My son works as a missionary in New Orleans and depends on a 260 Skid Steer for much of his work. One of the bucket cylinders is leaking from the gland so he was going to pull the cylinder and rebuild it. Problem is with the blind end attachment point. Evidently, there is a tapered sleeve that is internally threaded to accept the mounting bolt. This sleeve must be removed to allow cylinder removal. He has attempted to back out the bolt and drive the sleeve out with no success. The local JD dealer said he'd have to cut the sleeve out. I'm in Tennessee and cannot help out. Anyone have any experience with this? Thank You Very Much!!

Torch. Bigger hammer.

But honestly, tell him to leave the cylinder attached at that end. He just needs to get the new seal kit, remove the snapring/splitring from the gland, tap in the gland a little to expose the inner shoulder that the inner snapring sits against. clean that inner snap ring groove. Install the tapered orange removal seal. Yank the rod out.

The piston nut is usually about 1-5/16" wrench or socket size. Red loctite the nut when putting it back together.

I second rebuilding the cylinder on the machine as long as he can get the machine to a fairly clean environment to reduce contamination in the hydraulic system. I made a thread last spring on rebuilding the lift cylinders on my 317 skid steer, this thread may be of help to you. http://www.greentractortalk.com/forums/hydraulics/19684-lift-cylinder-rebuild-my-04-317-skid-steer.html

Beware Deere will only show on their computers one of the two seal kits for the 100/120 series cylinders. If in fact he has a 100/120 series cylinder he will need one of each of the kits listed below:

Kit part numbers:
AHC15630 ($52.92 each from Deere)
AH164325 ($18.13 each from Deere)

It is highly recommended that you also purchase CTM120519 which is a component technical manual on several series of John deere hydraulic cylinders, the 100/120 cylinders were adequately documented in this manual. Rough cost of this manual is about $100 from a Deere dealer, I could not find this manual from other sources online.
